DOM Standard
I would like to re-open the topic of declarative Shadow DOM. This has been discussed in the past, [here on WHATWG](https://github.com/whatwg/dom/issues/510), in W3C [here](https://github.com/w3c/webcomponents/blob/gh-pages/proposals/Declarative-Shadow-DOM.md) and [here](https://github.com/w3c/webcomponents/issues/71), and in [WICG](https://discourse.wicg.io/t/declarative-shadow-dom/1904/8). The...
Current specification of MutationObserver allows users to connect an observer to multiple target root nodes, but `disconnect` always acts on all of them. It makes it hard to write systems...
Add EventListener Sub Flags EventListeners allow the addition of a preset delay before firing the callback parameter (event throttling). However to reduce bandwith when polling a remote server, and because...
Linking issue from interventions WICG repo to keep continuity: WICG/interventions#63. Summarizing: There is no way to distinguish (from **inside of the listener**) whether event can be cancelable or no (or...
Apparently `TouchEvent` is always exposed in Chrome, but `document.createEvent("touchevent")` depends on the "touch events flag" (see https://github.com/w3c/touch-events/issues/64). Having said that, neither Firefox nor Safari expose `TouchEvent` so maybe Chrome should...
TreeWalker.nextNode loops forever if last node of a detached node tree is not accepted by the filter
For example, given: ```js var el = document.createElement("div"); var walker = document.createTreeWalker(document, 0, null); walker.currentNode = el; var next = walker.nextNode() ``` Following these steps: https://dom.spec.whatwg.org/#dom-treewalker-nextnode ``` 1. Let node...
Both https://github.com/whatwg/fetch/issues/179 and https://github.com/whatwg/fetch/issues/180 explain a desire for a timeout, but either the countdown gets reset based on networking activity (new chunk received) or it gets cancelled based on that...
This commit fixes a small typo in the id of the section https://dom.spec.whatwg.org/#action-versus-occurance. Since this id is probably used in many places, we kept a `` with the previous id...
This adds a fully active check in https://dom.spec.whatwg.org/#concept-event-listener-inner-invoke that skips running event listeners if the EventTarget's realm's global's document is not fully active. Blink, Gecko, and WebKit were all skipping...
This reverts commit c825ceaf3cb77943f487f85533d8be79bccd2fe3 and adds a new solution for `DocumentFragment` adoption on top. See #813 and #814 for context.
